Cancellations are counted against everything scheduled. Diverted flights are counted with them rather than as very late arrivals, which is why the on-time share and the cancellation rate do not add up to everything that happened.

Airline by airline

Airlines with at least 100 flights on BOS–DCA, busiest first. Same route, same weather, same air traffic — which makes this the fairest comparison on the site.
